Feb 09, 2007· For cohesive soils, I would crudely estimate a shrink factor of 2030%, with the swell factor maybe 5% larger. You should ask a professional estimator or conduct data gathering over several projects to refine the numbers. Jeff. RE: Shrink/swell factors for earthwork calculations
Sep 26, 2013· Swell is expressed as a percentage of natural volume, for example, if 10 yd 3 in the ground becomes 13 yd 3 after excavation, the swell factor is 30%. The following table lists swell factors for various engineering materials.
Easy diggable materials, like sand and gravel without clay content. Medium penetratable materials like gravel and well shot materials over 2 1/2" and lighter than classification Moist sand and gravel with high contents of wet clay. Still diggable with spade.
Building on a soil with a large swell factor can be costly. Soils with a high percentage of swelling clay can be difficult to grow plants in because water may pool on the surface. Calculating the swell factor of soil depends on the amount of water it can hold. The swell factor of some soils can be high and create enough force to break concrete.

Shrink and load factors are unit less and work the same for imperial and metric measurements as long as units used are identical. Since the shrink percentage is calculated from the bank state of the material it does not always have to be a negative % but will be smaller than the swell percentage.
The swell factor of materials such as sand and gravel is a variable which is dependent upon the type and compaction of the undisturbed (bank run) material.
